The Choppers are a crew of psychotic murderers in the Free Men gang. Their leader is Crazy Fat Ethel the most psychotic and murderous of them all. The crew specializes in breaking into houses, murdering everyone inside and eating all the food and stealing all the stuff. They maintain their place in the overall gang by doing dirty hits and eliminations for other crews, usually in exchange for pudding, lots of pudding.
Some people surmise that the Choppers, and the legendary Swish Plops of Blanchaven are one and the same, but there seems to be accounts of the Swish Plops that are older than Crazy Fat Ethel.
